LP-184: Detailed Phase 1a Results Demonstrate Clinical Proof-of-Concept & Activity

In September, Lantern announced the completion of enrollment and initial clinical results from its LP-184 Phase 1a clinical trial (NCT05933265), which successfully achieved all primary endpoints. The data across the 63 patients enrolled provided critical insights into safety, pharmacokinetics, biomarker correlations, and clinical activity that position LP-184 for advancement into targeted planned Phase 1b/2 studies.

Highlights of the Phase 1a Results:

• Clinical Benefit and Activity: The trial demonstrated clinical benefit in 48% of evaluable cancer patients treated at or above the therapeutic dose threshold. This encouraging activity was observed in heavily pretreated patients who had exhausted available standard-of-care therapies, representing proof-of-concept for LP-184's synthetic lethal mechanism.
• Safety Profile Supports Broad Development: LP-184 demonstrated a favorable safety and tolerability profile with minimal dose-limiting toxicities. The safety data support advancement into both monotherapy and combination therapy approaches with PARP inhibitors and immunotherapy agents.
• Activity in Difficult-to-Treat Cancers: Notable clinical benefits were observed in historically challenging tumor types including glioblastoma multiforme (GBM), gastrointestinal stromal tumor (GIST), and thymic carcinoma. Several patients have continued treatment beyond enrollment completion due to ongoing clinical benefit.
• Biomarker Strategy Strengthened: A key finding from the Phase 1a trial was the observation of marked tumor reductions in patients harboring specific DNA damage repair mutations, including CHK2, ATM, BRCA1, and STK11/KEAP1 alterations. These biomarker insights directly validate the AI-driven patient stratification approach developed through Lantern's RADR^® platform and support the use of genomic selection criteria in future trials.
• Pharmacokinetics Enable Dose Optimization: The trial successfully characterized LP-184's pharmacokinetic profile and established the recommended Phase 2 dose (RP2D) of 0.39 mg/kg, providing clear dosing guidance for planned Phase 1b/2 studies across multiple indications.

Based on the Phase 1a results and biomarker insights, Lantern is advancing development plans for LP-184 in three high-value indications:

• Triple-Negative Breast Cancer (TNBC), which represents a potential annual market opportunity exceeding $4 billion.
• NSCLC with STK11/KEAP1 Co-mutations: Phase 1b/2 study in a biomarker-defined subset of patients with mutations in STK11 and/or KEAP1 genes, representing a significant unmet medical need and a potential annual market approaching $1.5 billion.
• Bladder Cancer with DNA damage repair mutations in patients who have relapsed from SOC (standard of care) therapies, which is planned to be an investigator-led study initiating in Denmark.

Comprehensive results from the LP-184 Phase 1a trial are being prepared for submission to peer-reviewed journals and presentation at major oncology conferences. To provide additional insights and expert analysis of the clinical data, Lantern will host a Key Opinion Leader (KOL)-hosted scientific webinar on November 20, 2025 at 4:30 p.m. Eastern Time featuring detailed discussion of the Phase 1a results, biomarker findings, and clinical development strategy.

FDA Type C Meeting: Clarity in Regulatory Path for Pediatric CNS Cancer Program

A major third quarter regulatory milestone was the successful completion of a Type C meeting with the U.S. Food and Drug Administration during September. This meeting provided important guidance on the regulatory pathway and trial design for Starlight Therapeutics' – a wholly owned subsidiary of Lantern Pharma – planned pediatric clinical trial focused on CNS cancers, including Atypical Teratoid Rhabdoid Tumor (ATRT). The FDA provided constructive and supportive feedback on the proposed clinical trial structure.

Key outcomes from the Type C meeting included:

• Parallel ATRT Cohort Supported: The FDA confirmed support for a parallel cohort design specifically for ATRT patients, which will accelerate data collection in this ultra-rare pediatric population while maintaining statistical rigor.
• Combination Strategy Confirmed: The agency confirmed the potential incorporation of spironolactone as a combination agent with LP-184/STAR-001. This combination strategy is based on preclinical data demonstrating synergistic activity and RADR^® platform predictions of enhanced efficacy in pediatric brain tumors.
• Trial Design Alignment: The FDA provided guidance on appropriate endpoints, patient selection criteria, and safety monitoring approaches for this vulnerable pediatric population, enabling Starlight Therapeutics to finalize the clinical protocol with confidence in the regulatory pathway.

Regulatory Designations and Market Opportunity:

• LP-184, which is being developed as STAR-001 by Starlight Therapeutics in CNS cancers, has received both Rare Pediatric Disease Designation and Orphan Drug Designation from the FDA for ATRT, along with additional Rare Pediatric Disease Designations for hepatoblastoma, rhabdomyosarcoma, and malignant rhabdoid tumors. These designations underscore the urgent unmet need for innovative therapies in aggressive pediatric cancers and provide potential pathways for possible priority review vouchers upon approval.
• ATRT is an ultra-rare pediatric brain tumor with the genetic hallmark of SMARCB1 gene loss or dysfunction, affecting primarily children under age 3. Current treatment options are limited and associated with significant long-term toxicities, creating substantial demand for novel targeted approaches.

LP-300 HARMONIC™ Trial: Enrollment and Follow-Up Progress

The Phase 2 HARMONIC™ trial continued patient enrollment and follow-up during the third quarter across sites in the United States, Japan, and Taiwan. The trial evaluates LP-300 in combination with standard-of-care chemotherapy (carboplatin + pemetrexed) in never-smokers with NSCLC adenocarcinoma who have progressed after tyrosine kinase inhibitor therapy.

• In late July, Lantern announced the completion of enrollment in Japan for the HARMONIC™ trial across five clinical sites in Japan, including the National Cancer Center Tokyo.
• During November, clinical investigators associated with the HARMONIC™ trial presented data from the ongoing study at the 66th Annual Meeting of the Japan Lung Cancer Society. Dr. Jonathan Dowell from UT Southwestern Medical Center presented, “A Phase II Trial of LP-300 plus Carboplatin and Pemetrexed in TKI-Progressed NSCLC Patients”. Data from this presentation included the Asian and US cohorts of the study and will be further reviewed and presented in December by Lantern Pharma.
• Also, during the third quarter the company progressed with a change in clinical staffing and a transition of CRO services in Asia focused on significant cost reductions and efficiency in Taiwan.
• The study's strategic positioning in Asia, where never-smokers represent 33-40% of NSCLC cases compared to approximately 15% in Western populations, positions Lantern for potential regional partnerships and co-development opportunities. The treatment of never-smokers with NSCLC represents an estimated $4+ billion annual market opportunity with no specifically approved therapies for this patient population.

LP-284: LL&M Congress Presentation & Future Development Plans

During October Lantern presented clinical data from its ongoing LP-284 Phase 1 trial at the 25th Annual Lymphoma, Leukemia & Myeloma (LL&M) Congress in New York City. The presentation showcased the confirmed complete metabolic response in a heavily pretreated DLBCL patient and highlighted LP-284's novel mechanism of action and combination therapy potential.

LL&M Congress Impact and Additional Milestones:

• Presentation generated interest from biopharmaceutical companies and clinical investigators, with ongoing discussions focused on: combination therapy development with FDA-approved agents; post-immunotherapy treatment strategies; and LP-284's mechanistic differentiation. LP-284 has demonstrated particular lethality in cells with deficient DNA damage response, a targetable vulnerability in NHL.
